We like perfection.
Perfection is the ultimate achievement, there is nothing beyond.
Perfection is fully understood. It is not going to change, it is fact, we can rely upon it.
Perfection is final. Perfection is death.
Ideas can be perfect, and perfect ideas are easy to understand.
Perfect ideas are final and unchangeable. Perfect ideas are hard to correct, hard to refute.
Perfect ideas spread easily. They are helpful. They shed light on a little corner of our world, give it shape. They bring stability. They can be relied upon. Perfect ideas make good memes.
Perfect ideas are shared standards through which we act, interact, coordinate, cooperate. They don't change, so they are a solid base for habits, that make a bit of our life a little easier.
That we should not kill, is a perfect idea. So is racism. So are the ten commandments, so, for many, is love.
Thanks Lynoure for saying the right thing at the right time.
